net: netsec: Add metadata support for xdp mode
Set metadata size building the skb from xdp_buff in netsec driver.
netsec driver sets xdp headroom to NETSEC_RXBUF_HEADROOM:
NETSEC_RXBUF_HEADROOM max(XDP_PACKET_HEADROOM, NET_SKB_PAD) + NET_IP_ALIGN
so the headroom is large enough to contain xdp_frame and xdp metadata.
Please note this patch is just compiled tested.
